Question

即使My mobile tts引擎完全支持hindi textospeech，也无法将hindi设置为texttospeech的语音语言

        if(t1.isLanguageAvailable(new Locale("hi_IN"))==TextToSpeech.LANG_AVAILABLE)
            t1.setLanguage(new Locale ("hi_IN"));
        else
            Toast.makeText(getApplicationContext(), "Sorry! Text To Speech failed...", Toast.LENGTH_LONG).show();

Answer 1

首先，作为测试，在Android文本到语音设置中将文本设置为语音引擎。无需对代码进行任何更改，它应该成功地用印地语说话。如果没有，请检查日志输出以查看是否存在问题。

接下来，您的代码依赖于isLanguageAvailable()返回TextToSpeech.LANG_AVAILABLE，如果不是，您将不会尝试设置区域设置。还有许多其他可能的回应。检查下面两个case switch语句的日志输出。

    final Locale loc = new Locale("hin", "IND");

    // switch(tts.isLanguageAvailable(loc)){
    switch(tts.setLanguage(loc)){

        case TextToSpeech.LANG_AVAILABLE:
            Log.i("TAG", "LANG_AVAILABLE");
            break;
        case TextToSpeech.LANG_COUNTRY_AVAILABLE:
            Log.i("TAG", "LANG_COUNTRY_AVAILABLE");
            break;
        case TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE:
            Log.i("TAG", "LANG_COUNTRY_VAR_AVAILABLE");
            break;
        case TextToSpeech.LANG_MISSING_DATA:
            Log.i("TAG", "LANG_MISSING_DATA");
            break;
        case TextToSpeech.LANG_NOT_SUPPORTED:
            Log.i("TAG", "LANG_NOT_SUPPORTED");
            break;
    }

请注意，对isLanguageAvailable()的回复众所周知是不可靠的。有关原因，请参阅my edit on the answer here。

最后，确保在onInit()返回SUCCESS之后设置TTS对象的语言

Answer 2

尝试：

t1.setLanguage( new Locale( "hin", "IND", "variant" ) );

我希望它能够发挥作用，直到现在。

Answer 3

试试这个..

t1.setLanguage(new Locale ("hi","IN"));

而不是

t1.setLanguage(new Locale ("hi_IN"));

我希望它能奏效。

创建 TextToSpeech 类的对象后，您需要将其配置（或检查其可用状态/值）到 TextToSpeech.OnInitListener 的 onInit() 回调中。您将在那里获得有关 TextToSpeech 对象的可靠信息。

private fun initTextToSpeech(){
    tts = TextToSpeech(this,this) // TextToSpeech(context,listener)
}

override fun onInit(status: Int) {
    Log.e(TAG, "onInit: status: $status")
    if(status!=TextToSpeech.SUCCESS)return

    val locale = Locale("hi","IN")

    val isLangCountryAvailable = tts.isLanguageAvailable(locale)
    Log.e(TAG, "onInit: isLangCountryAvailable: $isLangCountryAvailable")

    if(isLangCountryAvailable==TextToSpeech.LANG_COUNTRY_AVAILABLE) {
        val setLanguageResult = tts.setLanguage(locale)
        Log.e(TAG, "onInit: setLanguageResult: $setLanguageResult")
    }

    Log.e(TAG, "onInit: availableLanguages: ${tts.availableLanguages}")
    Log.e(TAG, "onInit: voice: ${tts.voice}")

    binding.btnSpeak.isEnabled = status==TextToSpeech.SUCCESS
}

我在 onInit 回调上面得到的日志：

MainActivity: onInit: status: 0
MainActivity: onInit: isLangCountryAvailable: 1
MainActivity: onInit: setLanguageResult: 1
MainActivity: onInit: availableLanguages: [ko_KR, mr_IN, ru_RU, zh_TW, hu_HU,
